Support the new custom CloudWatch embedded metric format

[theburningmonk]

This is a Feature Proposal

Description

CloudWatch just announced a native format for tracking custom metrics through CloudWatch Logs: https://aws.amazon.com/about-aws/whats-new/2019/11/amazon-cloudwatch-launches-embedded-metric-format/

Maybe it's time to let you choose how you want to record those custom metrics from our libraries - i.e. the http client

@theburningmonk This would make a great additional to the power tools, is it still on the radar?

Additionally middy version 2.x provides an implementation of a middleware for cloudwatch-metrics (Embedded metric format), link: https://github.com/middyjs/middy/tree/main/packages/cloudwatch-metrics But given that middy version 1.x is incompatible with middy version 2.x , the middleware for cloudwatch-metrics (Embedded metric format) cannot be used together with dazn-power-tools. I have writtten some test cases , here: https://github.com/niko-achilles/cloudwatchMetrics-lambda-power-tools that proves this fact and came to conclusion that i needed to create a middy version 1.x cloudwatch-metrics midddleware (Embedded metric format) in order to use it with dazn-power-tools. That also mean that for the libraries - i.e http client , in order to support cloudwatch-metrics (Embedded metric format) a re-implementation is needed .

Any plans about supporting cloudwatch-metrics (Embedded metric format) as middy middleware with dazn-power-tools ?

These power tools now support middy 2.0, so https://github.com/middyjs/middy/tree/main/packages/cloudwatch-metrics probably solves this need now?
